Application mea september 27, 1920. seriai No. 413,010.

To all whom t may concern.'

Be it known that l, CHARLES P. SALGEE, a

citizen of the United States, residing at Philadelphia, in the county of PhiladelphiaJ and State of Pennsylvania, have invented new and useful Improvements in Fluid Engines, of which the following is a specification.

My present invention has reference to a fluid pressure operated engine.

My object is to produce a simple construction of engines of this character in which a simple but novel construction of parts actuated by fluid under pressure influences a piston to impart a` continuous reciprocatory movement thereto. A further object is to construct an engine or motor including a casing having an inner member both of which are ported and a slidable valve in the inner casing having heads thereon which divide the said inner casing into'an upper f and a lower compartment, the said valve having ports which are brought successively into operation by fluid admitted to either the upper or lower chambers, such fluid actuat- .ving the plunger for a greater length of travel than the valve so that the ports are brought into proper alignment to receive and to exhaust the fluid, spring means imparting an initial movement to the plunger, and said plunger carrying` a piston which projects through a stufling box at one end of the casing.

The foregoing, and other objects which will be apparent as 'the nature of the inven.. tion is better understood may be accomplished by a construction, combination and operative arrangement of parts, such `as is disclosed by the drawings 'which accompany and which form part of this application.

In the drawings z- Figure 1 is an. elevation of a fluid pressureengine constructed in accordance with this invention.

Figure 2 is a central vertical longitudinal sectional View through the same.

Figure 3 is a top plan view thereof.

Figure 4: is a sectional view approximately on the line 1-4 of Figure 2.

Figure 5 is a sectional view approximately on the line 5 5 of Figure 2.

Figure 6 is a bottom plan view.

Figure 7 is a vertical section of the valve.

Figure 8 is a perspective view of the plunger.

Figure 9 is a vertical section of the headed member which carries the cylinder that .forms one of the compartments of the oas- 111g.

rFigure 10 is a similar view of the tubular member that provides the second inner con` partment of the casing.

My improved construction of fluid operated engines includesan outer cylindrical easing 1 which is provided, on one of its sides with a longitudinally extending fluid receiving passage 2 that is ported, adjacent to its upper and lower ends, as indicated by the numerals 3 and t respectively. These ports d can be made by providing the outer wall of the passage with openings and inserting a suitable drill-therethrough, after which the openings may be plugged. By providing the casing with such openings, ports in other elements that are included in the improvement may be likewise made.

The tubular casing 1 has its upper or outer end open, the same being closed by a y head 5, the gasket 6 resting between the head and the said end of the casing, andfsecuring means, suchas bolts 7 passing through openings in the head and received in threaded orifices in the casing.` Thus the head compresses the gasket against the casing. The head is centrally provided with an opening that is'surrounded by van annular outstanding flange S which provides a stuflingbox, a suitable stuiiing 9 being arranged therein. The stuffing box has exterior threads which are engaged by interior threads on the flange of a cap nut 10.

The casing, at the side thereof opposite that provided with the passage 2 has, adjacent its ends fluid outlet ports 11 and 12 respectively, the same being arranged in alignment with ports 13 and 14 respectively that are formed in the side walls of 'the tubular members 15 and 16 respectively that provide the inner elements of the casing. rEhe tubular member 15 is integrally formed on the head 5, while the tubular member 16 has a closed end which rests on the rear or closed wallof the casing 1, vsecuring elements l? passing through the said closed end of the casing and entering the closed end of the tube 16, thus not only securing the tube in the casing, but properly centering the same. In this respect, it `should be stated that the elements 7 likewise properly position the tube 15 in the casing, that is the securing means hold both of the casings against turning, and therefore their ports in i proper alignment with the outlet ports 11 and 12. The tube- 15 has an inlet port 41S disposed opposite the port 8, and the tube 16 has an inlet port 19 disposed opposite the.v port Il. By reference to the drawings, it..

tween the tubular members 15 and 16 and the casing proper. The valve 21 is held against turningby forming the saine witha slot 22 within which is received a pin'23 that passes through the casing 1. The valve has outletports 24e' and 25 respectively and inlet ports 26 Vand 2T respectively.-

Garriedbyi theclosed end of the tube 16 is an inwardly extending pinv28. On the end of this pin there'is threadeda headedineniber 29 which contacts with a Washer 30 that is slidable on-the said pin 28, beingintluenced by a springl that surrounds the pin anu contacts with the washer and with the closed walloit the tubular member 16. Y

llhe inturnedllange'() of the valve 21 has depressions or angle walls which surround the passage therethrough aiidwliich providel contact elements or seats and 32` respectively, l'or the beveled'inner surfaceson the heads 38 and'll oi'i'aplunger-. The heads 33 'and Minay be adjustablysecured to thev stein which connectsy the same, the stem being,y however, pi'el'erably lformed'on the lower head land having a threaded end whichis.- receivedin a threadedbore in the inner Vface of the headBS.

Both olE the heads 33 and 3ft are prefer ably provided fwithf` annular depressions within which arel seated expansible gaskets 36 andfli'i respectively, the said gaskets beinglin contactingengagement with the respective tubes 15 and 16. The-head 84 has a depress-ion 38,in the outer face thereohlso that tliepiii QSVand-the headed element onV the end thereo maybe partly received in the said headl. The head 33 has. secured thereto-a piston rod 39 thatextends through the packing boa: at the outer` end of the cylinder: The piston rod has its outer end provided with a slottedihead 10, and received in the slotis an element 41 which is actuated onthe reciprocation o the piston rod. On the pistcii rod, andcontacting `with the outer :tace ofthe head ol' the plunger isia buer spring 42.

Connected in the mouth of the passage 2 is a. pipe The passage olfthisppipe is underthe control oLt avalve 111. The pipe is connected toailiiid supply and the fluid iny the valve 44 turned to permit ofthe. passage .of Huid through the pipe 13, it will be seen that theluid will. be admitted into the lower chamber in the casing which, i'or distinction,

.is indicated by the numeral Ll5, below the head Sil or the plunger. The fluid will cause the plunger to moved in an outwarddirect-ion until the head Se contacts with'the wall 32 el the ange20 on the valve 21. When the parts are in the position shown in the said Figure `2 the ports 13, 2&1 aiid'll are iii alignment, so Vthat A[luid which has.

been previously let into the upper compartine-ntf'll ofthe casing will exhaust. therethrough.y The contactingenga'ementof the.

C) D V D head viththe Vflange 20 will causev the valve tobe movedlongitudinally, bringing the port 2li oit the valve out of alignment..

withthe ports 11 and 13, and also bringing the port 26 in alignment with .the ports 3 and 1S. The headll is,.however, of sulilcient length to covertl'iese ports `so thatztheispring..

12 can be compressed before thev plunger is J 1 .r i inovedto .bring the saidheaci 33 ro uncover the ports. This movement oi the. valve',.of course, causes the rt 2? to be brought out ot register with the-inlet ports 4; and 19,.-but

the port 25 oi the sait valve is brought intov register with the poi-ts lflaiid 12,.:50 that the fluid. in the lou-fer compartment e5 will be. exhausted' through. these ports. The fluid nov." acts on thehead 33, causing the plungery to be iiiovediiian opposite direction, andv ii Z39 inward ofthev cas.

also moving the i ing. The heaili Bel is alsowo'l' length Vto cover the inlet ports 1.9, 27 and l, Ywhenfthe plunger has l n returned, so that vthe spring butler means are and compressed, to impart initial inovenient to the plunger and causeflhe head Seltl ireo'flto iincoverthe.v

The butler springs earried. by the plunger and by` they casing are sull'ieientlv `sti-.ongle overcome any triction which may existbetween the stu'liing boX and piston rod or` betweenV the headsfof the plunger and the inner sections of the casing 'liornied by the tubular members 15 and 16.
